The exploration of our software adopted MFC as hardware platform, Chinese Windows 2000 professional as operating system, Authorware 6.0 as multimedia development tool, Photoshop 6.0 , CorelDraw 10.0 as image disposal tool,Flash 5 as animation fabrication tool, Goldwave as voice dealingtool.
Urination sounds of 2 healthy men and 4 patients with abnormal urinary flow (2with prostatic hyperplasia, 1 with meatal stenosis and another 1 with meatal malformation) were recorded and analyzed with sound spectrograph.
This algorithm is provided with a sound theoretic basis, and its computing complexity is relatively lower and not strongly dependent on the data length.
Relationships between longitudinal and radial Picea genera sound vibration parameters
Longitudinal sawn wood are usually selected as samples in the study of sound properties of a musical instrument board.
Therefore, it is very important to evaluate the vibration properties of the board in the round, especially for the sound radiation characteristic of radial sawn timber and its relationship to longitudinal sawn timber.
However, for the national and international experts, researches on radial sawn timber and its role and function in sound emission have not yet been developed.
In speech signal processing systems, frame-energy based voice activity detection (VAD) method may be interfered with the background noise and non-stationary characteristic of the frame-energy in voice segment.
In order to demonstrate the approach, this paper integrates the emotion model into a system composed of voice recognition and a realistic facial model.
On Effectiveness of Static and Dynamic Signs in the Recognition of Voice Signals
The analysis is made of the effectiveness of various systems of voice signal signs in the framework of the model of a device of the automatic recognition of voice commands.
A composite system of signs that accounts for the static and the dynamic component of a voice process is suggested.
Experiments show that a 55.0 % relative reduction in frame error rate and a 98.5% relative reduction in sentence-breaking error rate are obtained when using multimodal VAD, compared to frame-energy based audio VAD.
For general unsteady motion of such a filament we give explicit formulas that express the velocity at a given point in terms of the intensity of the free vortices entering the audio signal audibility zone constructed for this point.
The output power of the signals is 10 and 75 W, respectively; the gain of the channel amplifiers is 40 dB; and the amplified signals are the video and audio signals of the TV channel 12.
It permits the directional radiation, and recording, of high-level audio-frequency sound.
Abstract self-explanatory films, which are series of frames/pictures with video, animation, audio, and other multimedia effects, are used for presentation of the method.
The origin of some acoustic phenomena in the arteries is connected by some with the propagation of discontinuities; these phenomena include Korotkov sounds, used in the determination of the arterial pressure of blood [1, 7].
A new method for estimating voice sounds transmitted to the chest wall in children and adolescents
The spectral characteristics of voice-transmitted sounds have been estimated in children and adolescents.
The frequency of the first spectral peak of the voice-transmitted sounds "tree, tree" (M ± SD) is 263.7 ± 7.82 and 253 ± 4.29 Hz at ages of 7-11 and 12-14 years, respectively.
